Description

The present invention, by specifying the position on the display screen using the pointing device, the operation control unit for operating the character, and relates to a program for implementing the operation control device.

  In recent years, various home game devices have been sold, and various games can be enjoyed at home. On the other hand, the spread of personal computers is remarkable, and it is entering an era where there is one computer in each household. However, a game using a personal computer is not as popular as a game using a home game device, although it can be used by purchasing only game software without purchasing a home game device.

  Usually, a game using a personal computer is advanced by operating a keyboard and a mouse. Users who are accustomed to operating a game controller of a home game device have resistance to the operation of the keyboard and mouse, and that the type of game is restricted due to the restriction of the operation. This is probably because it is not so popular.

  In particular, in a fighting game, it is necessary to quickly change the moving direction and the attacking direction of the character, but it is difficult to operate the character because it cannot be intuitively operated with the arrow keys of the keyboard. In addition, since the mouse has a small number of buttons, assignment of attack techniques to each button is restricted, and there is a problem that various attack techniques cannot be set.

  For this reason, game controllers dedicated to personal computers have been developed as means for operating games using personal computers.

  Hereinafter, as a preferred first embodiment of the present invention, a fighting game in which a player operates a main character to fight another character is referred to as a personal computer (hereinafter referred to as “game device”) in which the game program is installed. )) Will be described in detail by taking the case of implementation as an example.

  First, the hardware configuration of this embodiment will be described.

  FIG. 1 is a configuration diagram showing a game device provided with an operation control device according to the present invention. The game apparatus 1 includes a main body 11, a mouse 12, a monitor 13, and a disk 14.

  The main body 11 includes a control unit 111, a drawing processing unit 112, an audio processing unit 113, a disk drive unit 114, a hard disk device 115, and an I / O interface unit 116. The control unit 111 is connected to a drawing processing unit 112, an audio processing unit 113, and an I / O interface unit 116. In addition, a disk drive unit 114, a hard disk device 115, a mouse 12, and a monitor 13 are connected to the I / O interface unit 116.

  In the game apparatus 1, the disc 14 on which the fighting game program is recorded is mounted on the disc drive unit 114, and the game program and game data in the disc 14 are read from the disc drive unit 114 into a RAM 111 c (described later) in the control unit 111. It is. When the read game program is executed by a CPU 111a (described later), the player can enjoy the game contents. The player can advance the game by operating the mouse 12.

  Although the configuration of the mouse 12 will be described later, there are two types of operations for the mouse 12: a moving operation for moving the mouse 12 in the horizontal direction and a pressing / release operation for pressing / releasing a button provided on the mouse 12. is there. When the moving operation is performed, a movement signal is output from the mouse 12, and when the pressing / releasing operation is performed, a pressing / releasing signal is output from the mouse 12, respectively. Of these, the movement signal is used to move the pointer displayed on the screen of the monitor 13. In the present embodiment, the character is operated on the screen of the monitor 13 based on the positional relationship between the pointer and the character operated by the mouse 12 and the press / release signal, and displayed on the screen of the monitor 13. It is something to make progress. Details of the action of the character by operating the mouse 12 will be described later.

  The disc 14 is provided with a two-player mode in which two players play a match and a one-player mode in which the control unit 111 (pseudo player) in the game apparatus 1 is played. In the present embodiment, the case where the game is executed in the single-player mode is described. In the case of the two-player mode, two mice 12 are required.

  The control unit 111 has a microcomputer that controls the overall operation of the main body 11. The microcomputer includes a CPU 111a, a ROM 111b, a RAM 111c, and the like, and each unit is connected by a bus line. The CPU 111a performs overall control of the game progress by executing a game program read from the disk 14 to the RAM 111c by the disk drive unit 114.

  More specifically, when an operation signal (a signal output from a movement detection sensor and a button switch described later) by the player operating from the mouse 12 is input, the CPU 111a determines a predetermined value for the operation signal according to the game program. The game progress process is performed, and the result of the process is displayed on the monitor 13 as, for example, a three-dimensional image, and is output from the speaker 13a (described later) of the monitor 13 with sound effects.

  The ROM 111b stores a basic program indicating a basic function of the game apparatus 1 such as a disk loading function, a game program recorded on the disk 14, a procedure for reading game data, and the like. When the disk 14 is loaded in the disk drive unit 114, the CPU 111a operates the disk drive unit 114 according to the basic program stored in the ROM 111b, reads the game program and game data from the disk 14 into the RAM 111c, and sets the game start state.

  The RAM 111c provides an area for storing game programs and game data read from the disk 14 by the disk drive unit 114, and a work area for the CPU 111a to execute the game programs.

  The game program is configured by combining a plurality of programs. For example, the game program should be displayed on the game progress program for controlling the action of the character displayed on the monitor 13 based on the operation signal from the mouse 12 or the monitor 13. The graphic control program etc. which control a three-dimensional image are comprised.

  While the game is in progress, the position of each character and the position of the pointer operated by the mouse 12 are stored in the RAM 111c. In the present embodiment, the movement movement of the character is determined from the position of the pointer and the position of the character to be operated. Further, the position of the pointer when the button of the mouse 12 is pressed and the position of the pointer when the button is released thereafter are stored in the RAM 111c. In this embodiment, the attacking action of the character is determined from the position of the pointer when the button is pressed and the position of the pointer when the button is released.

  Based on an operation signal from the mouse 12, the CPU 111a reads a game program, image data, and the like from the disk 14 into the RAM 111c as necessary, and processes these data and executes the game program to the monitor 13. Determine the contents of the 3D image to be displayed.

  The drawing processing unit 112 performs various arithmetic processes necessary for the drawing process. The CPU 111 a determines an image to be displayed on the monitor 13, reads image data (character and background polygon data and texture data), light source data, and the like necessary for drawing the image from the RAM 111 c and supplies them to the drawing processing unit 112. . In addition, the CPU 111 a supplies an operation signal input from the mouse 12 to the drawing processing unit 112.

  The drawing processing unit 112, based on the image data and the operation signal supplied from the CPU 111a, and the data necessary for drawing (positional relationship between the character and the background, coordinates of the polygon constituting the character and the background on the screen of the monitor 13, A texture corresponding to each polygon and data such as reflection characteristics of each polygon are calculated, and image data of the game screen is created in a VRAM (not shown) in the drawing processing unit 112 based on the calculation result. The created image data of the game screen is output to the monitor 13 as a video signal and displayed. The drawing processing unit 112 also performs calculations for drawing a pointer operated by the mouse 12.

  The audio processing unit 113 performs various arithmetic processes necessary for processing for generating sound such as sound effects. When the CPU 111a determines a sound effect or BGM sound content to be output from the speaker 13a of the monitor 13, the CPU 111a outputs a voice command to the voice processing unit 113. The sound processing unit 113 reads out sound effects or BGM sound data from the RAM 111c based on a sound command from the CPU 111a, performs predetermined processing and D / A conversion, and then outputs the processed sound to the speaker 13a.

  In the case where the main body 11 is a normal personal computer that does not include a drawing processing processor or a voice processing processor, the drawing processing unit 112 and the voice processing unit 113 are realized by the CPU 111a and the RAM 111c.

  The disk drive unit 114 reads game programs and game data recorded on the disk 14.

  The hard disk device 115 is for recording information relating to game progress. The work area recording in the RAM 111c disappears when the game apparatus body 11 is turned off. The hard disk device 115 records information that should remain without being erased. When a “save data” command is issued from the player while the game is in progress or at the end of the game, the CPU 111 a records information regarding the game progress in the hard disk device 115. Specifically, information on the progress of the game includes information on the created original character and information on the game results. Information regarding the game progress recorded in the hard disk device 115 is read out as necessary at the start of the game. Information regarding the game progress may be recorded in a flash memory or the like connected to a USB terminal (not shown) instead of recording in the hard disk device 115.

  The I / O interface unit 116 transmits the game program and game data read by the disk drive unit 114, information related to the game progress read from the hard disk device 115, operation signals from the mouse 12, and the like to the control unit 111. Or a video signal, an audio signal, or the like from the control unit 111 is transmitted to the monitor 13.

  The mouse 12 is operated by the player in order to operate the character and make various settings relating to the game. The mouse 12 includes a trackball 12a, a left button 12b, and a right button 12c. The trackball 12a is a movement detection sensor composed of a ball provided on the bottom surface of the mouse 12 and a sensor for detecting the rotation direction and the rotation amount of the ball. The trackball 12a detects the moving direction and moving distance of the mouse 12 in the horizontal direction. The mouse 12 outputs the moving direction and moving distance to the control unit 111 as movement signals. The mouse 12 may be an optical mouse having a light emitting mechanism and a light receiving mechanism instead of the trackball 12a.

  Further, the mouse 12 outputs a pressing / release signal when the player presses the left button 12b or the right button 12c or releases the press. When the mouse 12 is operated by the player, the operation signal is transmitted to the control unit 111, and the character displayed on the monitor 13 performs a predetermined action. Examples of the predetermined operation include a movement operation such as running, walking, squatting, and jumping, and an attack operation such as scolding and kicking. In addition, a special technique is set according to the character, and this special technique can be executed by operating the mouse 12. The predetermined action of the character by operating the mouse 12 will be described later.

  The monitor 13 displays a game screen indicating the game progress state according to the video signal sent from the main body 11, or outputs sound such as sound effects from the speaker 13 a according to the audio signal sent from the main body 11. It is a device for. In the case of a so-called notebook personal computer, the main body 11 and the monitor 13 are integrated.

  The disk 14 is composed of, for example, a DVD-ROM or a CD-ROM. The disc 14 stores a game program and various data and image data necessary for executing the game program.

  Next, the movement of the character by the operation of the mouse 12 in this embodiment will be described.

  FIG. 2 is a diagram showing a screen display of one scene of the fighting game of the present embodiment. FIG. 2 is where the main character A and the opponent character B are fighting. A straight line E is displayed from the center point C of the main character A to the tip of the pointer D. A circle F and a circle G are displayed with the center point C as the center. The center point C, the pointer D, the straight line E, the circle F, and the circle G are marks for operating the main character A.

  The main character A is an operation target of the player, and the player operates the main character A by operating the mouse 12. The RAM 111c stores the coordinates of the center point C of the main character A (hereinafter referred to as “character coordinates”), and the main character A is displayed on the screen based on the character coordinates. Since the main character A is always displayed around the character coordinates, when the character coordinates are changed, the main character A is displayed so as to move accordingly.

  The pointer D is directly operated by the player using the mouse 12, and moves based on a movement signal output from the mouse 12 when the player moves the mouse 12 horizontally. The RAM 111c stores the coordinates of the position of the tip of the pointer D (hereinafter referred to as “pointer coordinates”), and the pointer D is displayed on the screen based on the pointer coordinates. When the movement signal is input from the mouse 12, the CPU 111a reads the pointer coordinates from the RAM 111c, and changes the pointer coordinates based on the movement signals. Since the pointer D is always displayed at the position of the pointer coordinates, it is displayed as if it is moving in accordance with the operation of the mouse 12.

  The straight line E is displayed so as to connect the center point C and the tip of the pointer D. Since the main character A moves as if the straight line E is pulled by a rubber string, the straight line E is hereinafter referred to as “rubber E”.

  The circle F is a circle centered on the center point C and having a radius of 1/4 of the horizontal length L of the display screen. The circle G is a circle centered on the center point C and having a radius of ½ of the horizontal length L of the display screen. The circle F and the circle G serve as a standard for changing the movement of the main character A at the position of the tip of the pointer D. The radii of the circle F and the circle G are not limited to these.

  Pointer coordinates and character coordinates are coordinates in a coordinate system in the game space, and a part of the game space is displayed on the display screen.

FIG. 3 is a diagram for explaining the game space. The game space is a three-dimensional space, but the characters A and B cannot move in the depth direction. Therefore, as shown in FIG. 3A, with respect to the positions of the characters A and B, the game space can be considered as a two-dimensional space without depth. This coordinate system has a predetermined range in the vertical direction (Y-axis direction) and the horizontal direction (X-axis direction). The positions of the characters A and B are represented by the game space coordinate system coordinates of the center points C _A and C _B of the characters A and B, respectively.

When displaying the characters A, B on the display screen, the character A in the game space coordinate system, the center point C _A of B, and toward the fixation point is a midpoint of C _B, the center point C _A, between C _B An image picked up from a camera position separated in proportion to the distance is drawn. That is, the characters A and B on the game space are perspective-projected on a virtual screen determined from the camera position and the imaging direction of the camera, and the image projected on the screen is displayed on the display screen. At this time, the position of the camera is set so that the entire two characters A and B who are competing are projected on the screen. Therefore, when both characters A and B are approaching, the camera images from the position approaching both characters A and B, so that both characters A and B are enlarged and displayed. Conversely, when both characters A and B are separated, the camera images from a position away from both characters A and B, so that both characters A and B are reduced and displayed. FIG. 3B is a screen display of the main character A and the opponent character B located in the lower left of FIG. 3A, and FIG. 3C is the main character A and the opponent character B of FIG. Is a screen display of the main character A ′ and the opponent character B ′ after moving to the lower right position in the game space.

  The main character A 'and partner character B' in FIG. 3C are positioned closer to each other than the main character A and partner character B in FIG. At this time, since the radius of the circle F ′ and the circle G ′ in FIG. 3C is based on the horizontal length L of the display screen, it is the same size as the circle F and the circle G in FIG. It becomes. Conversely, in the game space, the circle F ′ and the circle G ′ are smaller than the circle F and the circle G. The reason why the sizes of the circle F and the circle G are not changed on the display screen is to make the region have a constant size in the operation of the pointer D described later.

  The main character A moves differently depending on the positional relationship between the character coordinates and the pointer coordinates. The movement operation of the main character A corresponding to the positional relationship between the two coordinates will be described with reference to FIGS.

FIG. 4 is a diagram for explaining the position of the pointer coordinates with respect to the character coordinates. In FIG. 4, a point indicating the character coordinates is P _C , and a point indicating the pointer coordinates is P _P. As shown in FIG. 4, the game space is divided into 12 regions with the character coordinates as the center. That is, it is divided into three regions by the circle F and the circle G at that time. Furthermore, each region is represented by X
Clockwise with the positive direction of the axis (the direction from left to right in FIG. 4) being 0 °, 315 ° to 360 ° and 0 ° to less than 45 °, 45 ° to less than 135 °, The region is divided into four regions of a region of 135 ° or more and less than 225 °, a region of 225 ° or more and less than 315 °. The movement of the main character A is determined depending on which of these 12 areas the pointer coordinates are located.

  FIG. 5 is a moving action table for determining the moving action of the main character A based on the area where the pointer coordinates are located. The main character A is controlled to perform the movement operation set in the movement operation table. FIG. 5 shows a case where the opponent character B is in the positive direction of the X axis.

  When the pointer coordinates are located in the areas F1 to F4 in FIG. 4, the movement operation is “stop”, and the main character A does not move and is controlled to defend against the attack from the opponent character B. When the pointer coordinates are located in the areas G1 and H1 in FIG. 4, the movement action is “forward”, and the main character A is controlled to move forward toward the opponent character B. When the pointer coordinates are located in the regions G3 and H3 in FIG. 4, the movement action is “retreat”, and the main character A is controlled to retreat to the opposite side of the opponent character B. At this time, the movement speed is low when it is located in the areas G1 and G3, and the movement speed is high when it is located in the areas H1 and H3.

  When the pointer coordinates are located in the regions G2 and H2 in FIG. 4, the movement action is “squatting”, and the main character A is controlled to squat on the spot and prevent the opponent character B from attacking. When the pointer coordinates are located in the areas G4 and H4 in FIG. 4, the movement action is “jump”, and the main character A is controlled to jump and prevent the opponent character B from attacking. At this time, when it is located in the region G4, it is a low jump, and when it is located in the region H4, it is a high jump.

  When the opponent character B is in the negative direction of the X axis, the angle of each area is different from that in FIG. That is, the regions F1, G1, and H1 are 135 ° to less than 225 °, and the regions F3, G3, and H3 are 315 ° to less than 360 ° and 0 ° to less than 45 °.

  In the present embodiment, as shown in FIG. 4, the area is divided into four parts, top, bottom, left, and right, and the moving direction of the main character A is determined by the area where the pointer coordinates are located. The moving direction of the main character A can be designated intuitively. Further, in FIG. 2, the main character A moves so as to be pulled by the rubber E displayed between the center point C and the pointer D, so that the moving direction of the main character A can be recognized more intuitively. . Note that the area division is not limited to four, and may be further finely divided. In the present embodiment, the four regions are divided by 90 ° so as to be equal, but may be divided unevenly. For example, in order to make it difficult to perform jumping and squatting operations, the vertical direction may be 80 ° and the horizontal direction may be 100 °.

  In the present embodiment, as shown in FIG. 4, the area is divided into three by two circles F and G, and the moving speed of the main character A or the jump height is determined by the area where the pointer coordinates are located. Therefore, it is possible to intuitively specify the moving speed or jump height of the main character A by operating the pointer D with the mouse 12. The division of the region is not limited to three, and the movement speed or the jump height may be changed stepwise by dividing it further finely. Further, the area may be divided not by a circle but by another figure such as an ellipse or a square.

  In FIG. 2, instead of displaying the circle F and the circle G on the display screen, the color of the rubber E may be changed to replace the circle F and the circle G. For example, when the pointer coordinates are located in the areas F1 to F4, white, the case where the pointer coordinates are located in the areas G1 to G4 are green, and the case where the pointer coordinates are located in the areas H1 to H4 are red, the circle F and the circle G are displayed. Even if not, the area where the pointer coordinates are located can be determined by the color of the rubber E.

In the present embodiment, the game space is divided into areas around the character coordinates, and the movement action of the main character A is determined by referring to the table depending on which area the pointer coordinates are located. The method is not limited to this. For example, a configuration in which an angle formed by a line segment connecting the character coordinates and the pointer coordinates with the positive direction of the X axis and the length of the line segment is calculated, and the moving action of the main character A is determined by referring to the table. It is good.

Assuming that the character coordinates are P _C (X1, Y1) and the pointer coordinates are P _P (X2, Y2), the angle α formed by the line segment P _C P _P and the positive direction of the X axis is expressed by the following equation (1). Is done. Line segment P
The length of the _C P _P is expressed by the following equation (2).

The angle α determines the moving direction of the main character A, by comparison with the radius of the line segment P _C P length of the _P and the circle F and a circle G, determines the moving speed or jump height of main character A. At this time, it is necessary to convert the radii of the circle F and the circle G into lengths in the game space.

  Next, the attacking action of the main character A will be described with reference to FIG. 6, FIG. 7, and FIG. A special technique is set for the main character A apart from a simple punch or kick attack. These attack operations are designated using the left button 12b and the right button 12c of the mouse 12. When the left button 12b is pressed and released immediately, that is, when it is clicked, a kick is paid out. When the right button 12c is clicked, the punch is paid out. When each button is pressed and the mouse 12 is moved and the button is released, that is, dragged, a special technique that varies depending on the direction and length of the drag is delivered.

  FIG. 6 is a diagram showing a screen display in a state where the player has dragged in order to deliver the special move. The description of the same parts as in FIG. Compared to FIG. 2, the display position of the pointer D is changed because of dragging. Further, a technique bar H is displayed from the position of the pointer D where dragging is started to the position of the pointer D where dragging is ended. Immediately after this, an image is displayed in which the main character A delivers the special move determined from the direction and length of the drag. The direction and length of the drag are determined from pointer coordinates when the button is pressed (hereinafter referred to as “start point coordinates”) and pointer coordinates when the button is released (hereinafter referred to as “end point coordinates”). Is done.

FIG. 7 is a diagram for explaining the position of the end point coordinate with respect to the start point coordinate. In FIG. 7, a point indicating the start point coordinate is P _P1 and a point indicating the end point coordinate is P _P2 . As shown in FIG. 7, the game space is divided into seven regions with the start point coordinates as the center. A circle Q in FIG. 7 is a circle having a radius that is 1/8 of the horizontal length of the display screen centered on the start point coordinates, and a circle R is a horizontal length of the display screen centered on the start point coordinates. It is a circle having a radius of 1/2 of that.

The region R1 is a region between the circle Q and the circle R that is 315 ° to less than 360 ° and 0 ° to less than 45 ° clockwise with the positive direction of the X axis being 0 °. The region S1 is an area outside the circle R, which is 315 ° or more and less than 360 ° and 0 ° or more and less than 45 °. The region R2 is 70 ° or more and less than 110 °, and is a region between the circle Q and the circle R. The region S2 is a region that is 70 ° or more and less than 110 ° and is outside the circle R. The region R3 is not less than 135 ° and less than 225 °, and is a region between the circle Q and the circle R. The region S3 is a region that is 135 ° or more and less than 225 ° and is outside the circle R.

  The reason why the gaps are provided between the regions is to prevent unintentional special moves. The reason why the area inside the circle Q is provided is to distinguish the click from the drag. Clicking is the same as dragging in that it is an act of pressing and releasing a button. Therefore, if the distance between the start point coordinates and the end point coordinates is equal to or less than a predetermined value, it is regarded as a click rather than a drag. A region Q1 is a region of the gap and a region inside the circle Q. The attack action of the main character A is determined depending on which of the seven areas the end point coordinates are located.

  FIG. 8 is an attack action table for determining the attack action of the main character A based on the area where the end point coordinates are located. The main character A is controlled to perform an attack action set in the attack action table. The set attack action varies depending on the character selected by the player. FIG. 8 shows a case where the opponent character B is in the positive direction of the X axis.

  When dragging with the right button 12c and the end point coordinates are located in the regions R1 and S1 in FIG. 7, the attack action is “wave fist”, and the main character A attacks the wave fist toward the opponent character B. To be controlled. When dragging with the left button 12b and the end point coordinates are located in the regions R2 and S2 of FIG. 7, the attacking action is 'Tornado whirlwind leg', and the main character A moves toward the opponent character B with the tornado whirlwind leg. Controlled to attack. When dragging with the right button 12c and the end point coordinates are located in the regions R3 and S3 of FIG. 7, the attack action is “Sho Ryu Fist”, and the main character A attacks the opponent character B with the Ryu dragon fist attack. To be controlled.

In the above description, when the end point coordinates are located in the regions R1, R2, and R3, the attack power of each of the special moves is small, and when the end point coordinates are located in the regions S1, S2, and S3, the attack power of each of the special moves is controlled to be large. The If it is not set in FIG. 8, for example, if the end point coordinates are located in the region Q1 in FIG. 7, or if the end point coordinates are located in the region R2 in FIG. Is not set. At this time, as in the case of clicking, the control is performed so that the kick is paid out in the case of the left button 12b and the punch is paid out in the case of the right button 12c.

  The attack action table when the opponent character B is in the negative direction of the X axis is different in angle of each area from that of FIG. That is, the regions R1 and S1 are 135 ° to less than 225 °, and the regions R3 and S3 are 315 ° to less than 360 ° and 0 ° to less than 45 °.

  In the present embodiment, as shown in FIG. 7, the region is divided around the drag start point coordinates, and the type of the special move that the main character A delivers is determined by the drag end point coordinates. Therefore, a plurality of types of special moves can be performed by operating the mouse 12. In each of the special moves, the right button 12c is assigned to those related to the punch, and the left button 12b is assigned to those related to the kick. In addition, each special move is assigned so that the one toward the opponent character B is dragged in that direction, and the one related to the jump is dragged upward. Therefore, the player can intuitively deliver the desired special technique.

  The area may be divided according to the number of types of special moves that are set. In addition, the angle of the area may be reduced to make it difficult to perform the necessary special technique.

  In the present embodiment, the attack power of the special move is determined depending on whether the end point coordinates are located inside or outside the circle R. Therefore, the attack power of the special move is determined by operating the pointer D with the mouse 12. It can be specified intuitively. Note that the area may be further divided and the attack power of the special move may be changed stepwise. Further, the area may be divided not by a circle but by another figure such as an ellipse or a square.

In the present embodiment, as shown in FIG. 6, the circle Q and the circle R are not displayed on the display screen. Instead, by changing the color of the technique bar H, the player can intuitively recognize the magnitude of the attack power of the deadly technique depending on the length of the drag. That is, when the end point coordinates are located in the area Q1, the color of the technique bar H is white, indicating that the special technique cannot be executed, and when the end point coordinates are located in the areas R1 to R3, the color of the technique bar H is This means that a special move with a low attack power is green, and if the end point coordinates are located in the areas S1 to S3, the color of the skill bar H is red and a special move with a high attack power can be executed. Represents.

  However, when the buttons 12b and 12c of the mouse 12 are pressed, the circle F and the circle G are not displayed, and the circle Q and the center of the tip of the pointer D when the buttons 12b and 12c are pressed are centered. A circle R may be displayed. In this case, the technique bar H may be displayed or may not be displayed.

In the present embodiment, the game space is divided into regions around the start point coordinates, and the attack action of the main character A is determined by referring to the table depending on which region the end point coordinates are located. Absent. For example, the angle formed by the line segment connecting the start point coordinate and the end point coordinate with the positive direction of the X axis and the length of the line segment are calculated, and the attack action of the main character A is determined by referring to the table. It is good.

Assuming that the start point coordinates are P _P1 (X3, Y3) and the end point coordinates are P _P2 (X4, Y4), the angle β formed by the line segment P _P1 P _P2 and the positive direction of the X axis is expressed by the following equation (3). Is done. The length of the line segment P _P1 P _P2 is expressed by the following equation (4).

The type of the special move is determined by the angle β, and the attack power of the special move is determined by comparing the length of the line segment P _P1 P _P2 with the radius of the circle Q and the circle R. At this time, it is necessary to convert the radii of the circle Q and the circle R into lengths in the game space.

  In the present embodiment, the coordinate system of the game space is expressed by a Cartesian coordinate system, but may be expressed by a polar coordinate system.

  Next, a processing procedure of a pressing operation determination process that is executed by the game device according to the present embodiment and determines a process for the pressing operation of the mouse button will be described with reference to a flowchart shown in FIG.

  FIG. 9 is a flowchart showing the pressing operation determination process. This process is a process that is called and executed periodically, determines whether the left button 12b or the right button 12c of the mouse 12 is pressed, and moves the main character A or performs an attack action accordingly. The processing is performed.

  First, it is determined whether or not the pressing flag is 'ON' (S1). The pressing flag is a flag that is set to “ON” when a pressing signal is input from the mouse 12 and that is set to “OFF” when a release signal is input. That is, it is determined whether or not the button is being pressed. If the pressing flag is 'OFF' (S1: NO), it is determined whether or not the button of the mouse 12 has been pressed (S2). That is, it is determined whether or not a pressing signal is input from the mouse 12. When not pressed (S2: NO), the character coordinates are read from the RAM 111c, and the game space area is divided by these coordinates (S3). Actually, a boundary line for dividing each region is determined. Next, pointer coordinates are read from the RAM 111c, and an area where the coordinates are located is determined (S4). Actually, the area where the pointer coordinates are located is determined based on which side of the boundary line dividing each area. Next, the movement operation table (see FIG. 5) is referred to, and the movement operation corresponding to the area where the pointer coordinates are located is determined (S5). Next, a moving operation process corresponding to the determined moving operation is executed (S6), and the pressing operation determination process is ended.

In the moving operation process, a preparation process for displaying an image corresponding to the determined moving operation is performed. If the determined movement action is “forward”, the X-axis component of the character coordinates is increased.
The amount of increase in the X-axis component is set to be larger when “forward (running)” than when “forward (walking)”. When the determined movement motion is “retreat”, the X-axis component of the character coordinates is decreased. The amount of decrease in the X-axis component is set to be larger in the case of “retreat (run)” than in the case of “retreat (walk)”. The changed character coordinates are overwritten in the RAM 111c.

  When the determined movement operation is “squatting” or “jumping”, the Y-axis component of the character coordinates is changed. At this time, the Y-axis component of the character coordinates increases once and decreases when 'squatting', and decreases and increases once when 'jumping'. The Y-axis component when the operation ends is the same as before the operation starts. In the case of ‘jump (higher)’ than in the case of ‘jump (lower)’, the Y-axis component is decreased and increased. Since the 'squatting' and 'jumping' operations are a series of continuous operations, the pressing operation determination process is not performed during this operation, and only the moving operation process is continued.

  In the drawing process executed after the moving action process, an image corresponding to the determined moving action is drawn around the position on the display screen corresponding to the character coordinates. As a result, an image in which the main character A is performing the determined moving motion is displayed on the display screen.

  In step S2, when the button of the mouse 12 is pressed (S2: YES), the pressing flag is set to 'ON' (S7). Next, pointer coordinates are read from the RAM 111c, and the coordinates are stored in the RAM 111c as start point coordinates (S8), and the pressing operation determination process is terminated.

  In step S1, if the pressing flag is 'ON' (S1: YES), it is determined whether or not the pressed button of the mouse 12 is released (S9). That is, it is determined whether or not an open signal is input from the mouse 12. When it is not opened (S9: NO), the pressing operation determination process is terminated. When it is opened (S9: YES), the pressing flag is set to “OFF” (S10). Next, pointer coordinates are read from the RAM 111c, and the coordinates are stored in the RAM 111c as end point coordinates (S11).

Next, the starting point coordinates are read from the RAM 111c, and the area of the game space is divided by these coordinates (S12). Actually, a boundary line for dividing each region is determined. Next, the end point coordinates are read from the RAM 111c, and the area where the coordinates are located is determined (S13). Actually, the area where the end point coordinates are located is determined based on which side of the boundary line dividing each area. Next, referring to the attack action table (see FIG. 8 ), the attack action corresponding to the region where the end point coordinates are located is determined (S14). Next, an attack action process corresponding to the determined attack action is executed (S15), and the pressing operation determination process is terminated.

  In the attack action process, a preparation process for displaying a video corresponding to the determined attack action is performed. That is, it is determined from the positional relationship with the opponent character B whether the attack action is effective. Based on the determination result, an image of the opponent character B used for a drawing process to be executed later is determined, and a damage value of the opponent character B is calculated. Since each attack operation is a series of continuous operations, the pressing operation determination process is not performed during this operation, and only the attack operation process is continued.

  In the drawing process executed after the attack action process, an image corresponding to the determined attack action is drawn around the position on the display screen corresponding to the character coordinates. As a result, a video of the main character A performing the determined attack action is displayed on the display screen. At this time, the opponent character B is also drawn with an image corresponding to the damage to the attacking action, so that an image in which the opponent character B is damaged by the attacking action is also displayed on the display screen.

  In the first embodiment, the start point coordinates and the end point coordinates are determined by a drag operation. However, the present invention is not limited to this. For example, the start point coordinates may be determined by a click operation, and the end point coordinates may be determined by a click operation immediately thereafter. The timing for determining the start point coordinates and the end point coordinates in this case may be the input timing of the pressing signal in the click operation or the input timing of the release signal. Also, the determination timing of the start point coordinate is the input timing of the pressing signal in the first click operation, the determination timing of the end point coordinate is the input timing of the release signal in the second click operation, and the determination timing of the start point coordinates is the first timing The input timing of the release signal in the click operation may be used, and the determination timing of the end point coordinates may be the input timing of the pressing signal in the second click operation.

  In this case, it is necessary to distinguish from a click operation for feeding a punch or kick. For example, if a predetermined time elapses from the first click operation, it is determined that the next click operation is a click operation for feeding out a punch or kick, and if the next click operation is performed before the predetermined time elapses, it will It may be determined as an operation, and the pointer coordinates at each click may be set as the start point coordinates and the end point coordinates, respectively.

  Further, the determination may be made based on the distance between the pointer coordinates at the time of each click. That is, when the distance is less than or equal to a predetermined value, the second click operation is also determined as a click operation for delivering a punch or kick, and when the distance is greater than a predetermined value, it is determined as an operation for a special move, You may make it the pointer coordinate at the time of each click be a start point coordinate and an end point coordinate, respectively.

  Rather than punching or kicking with each click operation, the start point coordinates are determined by the first click operation, the end point coordinates are determined by the second click operation, and the punch and kick are included by the start point coordinates and the end point coordinates. The attack action may be determined.

  Alternatively, the start point coordinates may be determined by clicking the left button 12b, and the end point coordinates may be determined by clicking the right button 12c immediately thereafter. Also in this case, the click operation for punching and kicking and the operation for the special move are performed according to the elapsed time from the click operation of the left button 12b to the click operation of the right button 12c and the distance between the start point coordinate and the end point coordinate. You may make it discriminate | determine.

  In the first embodiment, the case where the mouse is used as the operation means has been described. However, the present invention is not limited to this, and a pointing device that can specify the position on the display screen may be used. For example, in the case of a notebook computer to which a mouse is not connected, a pointing stick or a touch pad may be used. Further, since it is possible to enjoy an operation method different from the conventional fighting game in which the main character is directly operated, the game controller can be configured to use only two buttons by operating the pointer with a lever.

  In the first embodiment, the case where the game software is implemented in a personal computer is described. However, the present invention is not limited to this. The present invention can also be applied to a home game device, a portable game device, and an arcade game device. Also in these game apparatuses, the same character operation method as that in the first embodiment can be enjoyed.

  For example, in a home game device, a mouse may be connected, or a pointer may be operated using a connected game controller. Alternatively, the pointer may be operated with a pointing device such as a Wii remote controller (registered trademark).

  A portable game device such as the Nintendo DS (registered trademark) provided with a transparent touch panel so as to cover the display screen can also enjoy the same character operation method as in the first embodiment. .

  FIG. 10 is a configuration diagram showing a portable game device 1 ′ according to the second embodiment provided with the operation control device according to the present invention. In FIG. 10, the same or similar elements as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment. The game device 1 ′ includes operation buttons 13 e and a touch panel 13 d instead of the mouse 12 as operation means, and a first display device 13 b and a second display device 13 c instead of the monitor 13. . The main body 11 is not provided with a hard disk device 115, and a driver 114 ′ is provided instead of the disk drive unit 114. The game program and game data are read from the game media 14 ′ instead of the disk 14. Hereinafter, description of portions common to the game apparatus 1 of the first embodiment will be omitted.

  The touch panel 13d has a large number of micro capacitors or micro resistors arranged in a grid pattern on the panel surface. By touching the panel surface directly with a finger or a touch pen 13f, the micro capacitor or micro resistance at the contact position is changed, and the change is made. This is an input device for inputting information to the CPU 111a.

  The CPU 111a calculates a touch position on the panel surface based on touch information input from the touch panel 13d (change information of a resistor or a capacitor serving as a sensor).

  On the panel surface, as shown in FIG. 11A, the upper left corner is the origin 0 and the y axis is set downward and the x axis is set to the right. A sensor position (x, y) is defined for a sensor such as a capacitor. For example, when the player touches the p-point portion of the touch panel 13d with the touch pen 13f, the contact area includes a plurality of sensors as shown in FIG. A signal is input to the CPU 111a.

  The CPU 111a calculates the coordinates (x, y) of the sensor that has made contact from the input signal, calculates the center position of the contact area from these coordinates, and recognizes the calculation result as information on the contact position. For example, when the range in the x-axis direction of the contacted region is xmin to xmax and the range in the y-axis direction is ymin to ymax, the CPU 111a determines ((xmin + xmax) / 2, (ymin + ymax) / 2) as the contact position p. Calculated as the coordinates of.

The touch panel 13d is provided so as to cover the surface of the display screen of the second display device 13c is transparent, the coordinates on the display screen coordinates and a touch panel 13d of the second display device 13c is associated. Therefore, the position on the display screen of the second display device 13c can be specified by touching the panel surface of the touch panel 13d with the touch pen 13f or the like.

  The operation button 13e transmits a player's instruction to the CPU 111a when pressed by the player. The operation button 13e is used to specify a selection on the menu screen or the selection screen, a cross key for operating the main character, a start point coordinate, and an end point coordinate. There are four buttons A, B, X, Y, etc.

In the present embodiment, a pointer is displayed at pointer coordinates corresponding to a place touched directly with the touch pen 13f or the like on the display screen of the second display device 13c. The movement movement of the main character is determined in accordance with the character coordinates indicating the position of the main character and the pointer coordinates, as in the first embodiment. Further, the attacking action may be determined according to a start point coordinate that is a pointer coordinate when a predetermined button of the operation buttons 13e is pressed and an end point coordinate that is a pointer coordinate when the button is released. This is the same as in the first embodiment.

  If the position touched on the panel surface of the touch panel 13d with the touch pen 13f is a start point coordinate, the panel surface is traced with the touch pen 13f, and then the position where the touch pen 13f is separated from the panel surface is the end point coordinate, the attack operation In this designation, the pressing operation of a predetermined button becomes unnecessary. In addition, since the start point coordinates and end point coordinates can be designated directly on the screen, there is no need to display a pointer. In this case, the operation of the touch panel 13d cannot be used to distinguish between the designation of the attacking action and the designation of the moving action. Therefore, if the main character is directly operated using the “cross key” of the operation buttons 13e. Good.
